Diameter be more than the nut 1 diameter；The following table of the sheet body structure 3 tilts downwards；The sheet body structure 3 with it is described
The joining place of screw rod 1 is equipped with inside groove 4.
Further, the thickness of the nut 2 and its direct length are identical on dimensional values.
Further, the thickness of the sheet body structure 3 is 1.5 times to 2 times of standard component plain cushion thickness,
In, standard component plain cushion refers to what Shanghai hardware purchasing and supply station was compiled《Practical hardware handbook》(book number：Described in 15119-1277)
Each model plain cushion, the standard component thickness is that the specific thickness of plain cushion of each model in this book (is specifically shown in
Page 7.35 to page 7.36).
Further, 3 lower surface of sheet body structure tilts downwards 2.5 ° along from center to edge direction ---
3.5 °, the upper surface of the sheet body structure 3 tilts downwards 30 ° from center to edge direction --- and 45 °.
Further, the sheet body structure 3 and the joining place of the screw rod 1 are equipped with along the screw rod cricoid inside groove of 1 one weeks
4。
Further, the depth of the inside groove 4 is 0.4 times to 0.68 times of 3 thickness of sheet body structure.
The new new check bolt of this practicality, ratio and screw rod its length between screw rod and nut with
The ratio that diameter is shown in meets what Shanghai hardware purchasing and supply station was compiled《Practical hardware handbook》(book number：Described in 15119-1277)
National standard dimension scale.
The utility model advantageous effect：
The utility model proposes a kind of check bolt it is simple in structure, easy to process, the anti-untwisting of the conventional bolt of omission
Structure --- spring pad, by setting the sheet body structure tilted down and inside groove, to increase nut anti-loosing effect, anti-loosing effect pole
It is good., it is necessary to which the torque of bigger can just remove after bolt described in the utility model is fastened by prescribed torque, illustrate the utility model
The fastening effect and anti-loosing effect of the bolt are very good.
